Y., a corporation of New York Application August 21, 1946, Serial No. 691,903 In Great Britain August 31, 1945 6 Claims. 1

The present invention relates to an apparatus for the deodorising of the atmosphere.

An object of the present invention is to provide means whereby the atmosphere is automatically periodically given a charge of a volatile deodorant at times when a quantity of water is fiushed through a pipe.

According to the present invention liquid is periodically passed into the base of a container having a pad or wad of, or impregnated with, a volatile material at its upper outer end, to force air in said container through said wad or pad, whereupon said liquid is withdrawn from said container to recharge it with air.

A convenient form of device consists of a chamber having a support for a disinfectant volatile block or impregnated pad at its top open end which may be covered by a perforated cover and which is either directly connected at its lower end to a water flush pipe or connected thereto by a connecting pipe, so that water periodically passing down said pipe will in some measure percolate to the interior of said chamber and drive up the air enclosed therein over the surface of the said pad or wad into the atmosphere and then, as the water flush ceases, water will exhaust itself from the said chamber to allow a fresh charge of air from the atmosphere to enter the chamber.

The invention is further described. with reference to the accompanying drawings, in which:

Fig. 1 is a sectional elevation of one form of construction,

Fig. 2 is a corresponding sectional plan view,

Fig. 3 is a view corresponding to Fig. 1 in outside elevation.

A container l is open at its top end and closed by means of a cap 2 having a number of perforations, slits or other openings 3, this cap preferably being locked securely in position. Suspended within the top of the container I is a tray or basket 4 for the support of a block, pad or w'ad 5 which may itself be of a volatile disinfectant or made of fibrous material impregnated with a volatile disinfectant or deodorant. The container may be either connected by a pipe at its lower end to an opening in a water pipe 6 down which water is periodically flushed as from a cistern, or the container may be remotely disposed and connected thereto by a connecting pipe. In the arrangement shown, the pipe 6 has an opening through which projects a scoop 8 in the form of a tube having a bafiie end passing through a gland on a flange 9 forming part of a clamping bracket l attaching the container l to the pipe 6. This tube or scoop 8 may be rotated about its own axis to vary the cross sectional area of any vertical projection presented to water passing down the tube t, either by dismantling the clamps H3 or again from within the interior of the casing i after the cap 2 and basket 4 are removed.

Adjustable throttle means such as a set-screw it may be provided to vary the cross sectional area of this connection formed by the tube 8 from the pipe 6 into the container I.

Now it will be seen that every time a charge of water falls down the pipe 6, a similar proportion of this water will pass through the scoop end of the tube 8 and into the container l displacing air therein and forcing it upwards through holes in a solid block of disinfectant or deodorant or through the interstices of a fibrous pad suspended in the cage 4, which pad will be impregnated with disinfectant or deodorant, and thus into the atmosphere through the openings 3 in the cap 2; and as the charge of water passing down the pipe 6 becomes exhausted, then the charge of water which has passed into the container I will fiow back from this container into the pipe 6 drawing in a fresh charge of air, so that the apparatus is then in a state for a further operation on the next flushing of water through the pipe 6.

I declare that what I claim is:

1. An apparatus for use in conjunction with a toilet installation including a flush pipe through which a periodic supply of water is passed, said apparatus serving for deodorizing the surrounding atmosphere and comprising, in combination, a vertically extending container forming a vertically extending pump chamber; at least one opening in the upper wall portion of said container communicating with the surrounding atmosphere so as to permit free entry and exit of air into and from said pump chamber formed Within said container; a connecting pipe passing through the lower wall portion of said container firmly secured to the same and communicating at its inner end with said pump chamber within said container; means for securing said container to a flush pipe in such a manner that the other end of said connecting pipe reaches into said flush pipe permitting entry of water into said connecting pipe and through the same into said pump chamber withinsaid container each time water is passed through said flush pipe, thereby forcing during such passage of water through said flush pipe part of said water to enter said container rising within said pump odorant resulting in partial absorption of said deodorant by said air, while during each rise of the water in said pump chamber during each periodic passage of Water through said flush pipe at least part of the deodorant-containing air in said pump chamber is forced past said highly volatile deodorantincreasing its deodorant content-and expelled through said opening in the upper wall portion of said container, automatica-lly deodorizing the surrounding atmosphere during each passage of Water through said flush pipe.

2; An apparatus of the type disclosed in claim 1 in which said supply of highly volatile deodorant consists of a fibrous pad with the deodorant absorbed by said pad.

3. An apparatus of the type disclosed in claim 1 in which said means for securing said container to a flush pipe consist of a clamping bracket secured to the connecting pipe and adapted to be secured to the flush pipe.

4. An apparatus of the type disclosed in claim 1 in which said connecting pipe has an oblique end reaching into said flush pipe so as to force water passing through said flush pipe to enter said connecting pipe.

5. An apparatus of the type disclosed in claim 1 in which means are provided for regulating the cross sectional area of said connecting pipe.

6. An apparatus of the type disclosed in claim 1 in'which said container is provided with a cover and the opening provided in the upper wall portion of the container is arranged in said cover.
